Mechanical vibration - Rotor balancing - Part 1: Introduction (ISO/DIS 21940-1:2018); Text in German and English


This document provides an introduction to balancing and directs the user through the available standards associated with rotor balancing, and gives guidance on which of these standards should be used. Balancing is explained in a general manner, as well as the unbalance of a rotor. A certain representation of the unbalance is recommended for an easier understanding of the necessary unbalance corrections. Individual procedures are not included here as these are found in the appropriate standards which are listed in this document.
